Having survived yesterday’s fly-by, follow the live-briefing from the Nasa New Horizons mission to Pluto as they reveal the first hi-resolution images from the dwarf planet system nearly 5 billion km away. Adds The big news is that Pluto, and Charon, may still be geologically active. There are 3,500metre (11,000feet) high water-ice mountains on the more…

Nasa’s New Horizons mission spacecraft is now within two days journey time to the dwarf planet Pluto and its complex system of 5 moons. [Image credit: NASA, ESA, and M. Showalter (SETI Institute)] Travelling at 14km/s, New Horizons’ swift fly-by of the dwarf planet is scheduled to take place on Tuesday 14 July, at more…

A brief musical interlude, accompanied by a selection of wondrous time-lapse videos, old and new, from the International Space Station, by NASACrewEarthObs. Full-screen mode recommended. Enjoy! [Credit: Image Science and Analysis Laboratory, NASA Johnson Space Center.] The final video clip shows the surprisingly robust sun-grazing Comet Lovejoy as it emerged triumphant from its close encounter with Sol in December 2011.

In March Nasa’s Dawn spacecraft became the first man-made object to go into orbit around a dwarf planet – Ceres, at 950km across, the largest object in the main asteroid belt. As I mentioned at the time… [Image credit: Nasa/JPL] Using images taken during Dawn’s first mapping orbit at Ceres, Nasa’s Jet Propulsion Laboratory have produced more…

…and out of control… The BBC reports on the Russian unmanned cargo ship delivering supplies to the International Space Station that mission control has lost contact with and is now in a uncontrolled spin. Or, as RTÉ says, it’s ‘plunging back to Earth’. Here’s the view from a camera on-board the spacecraft. From the BBC report more…

Or, like me, cloud cover obscured the solar eclipse of 20 March 2015. Here’s probably the best view of this morning’s event, from ESA’s Sun-watching Proba-2 mini-satellite. [Image credit: ESA/ROB] And via ESA on YouTube. As Europe enjoyed a partial solar eclipse on the morning of Friday 20 March 2015, ESA’s Sun-watching Proba-2 minisatellite had a ringside more…

The BBC’s Stargazing Live returns tonight, 8pm BBC 2, with three consecutive nights of live programmes to coincide with the total solar eclipse on Friday 20 March 2015. [It is an annual series! – Ed]. Stargazing Live is, yes. Not necessarily total solar eclipses, though. And this solar eclipse is the only one, total or otherwise, to be more…

On Friday afternoon [GMT], ahead of Ireland cricketers’ epic encounter with Zimbabwe, Nasa’s Dawn spacecraft became the first man-made object to go into orbit around a dwarf planet – Ceres, at 950km across, the largest object in the main asteroid belt. [Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA] From the associated text The slim crescent of Ceres smiles back as the more…

[Image credit: ESA/Rosetta/Philae/CIVA] The ESA Rosetta probe has been on a long journey – spotted en route briefly on Slugger in 2008, and more leisurely in 2010 as it took time out from its mission to the Comet 67P/Churyumov-Gerasimenko to take a look at the asteroid Lutetia. Ten years after launch, it’s now orbiting its designated more…

Four years after its work began, and following last year’s three years in three minutes, Nasa have released another wondrous short video of a year of selected solar activity as viewed by the Solar Dynamics Observatory. Video via Nasa Goddard. Full-screen viewing recommended. Stunning. [Credit: NASA Solar Dynamics Observatory. Music: Stella Maris courtesy of Moby Gratis] The sun more…

Curiosity may have been on the surface of Mars for over a year, but ESA’s Mars Express has been in orbit around the Red Planet for almost a decade. It’s one of a number of ways Mars is being observed, up close and personal. And, like the Hi-RISE camera on Nasa’s Mars Reconnaissance Orbiter, Mars Express has some specialised instruments more…

As the Guardian’s GrrlScientist says, “Wow. Just wow.” And, “Oh, I recommend “full screen” mode.” Indeed. Adds – If you watch closely you can see Ireland and the UK pass underneath at around 2mins 30secs in. Time-Lapse | Earth from Bruce W. Berry Jr on Vimeo.

One year ago, after “seven minutes of terror“, Nasa’s Mars Science Laboratory, the 900kg rover Curiosity, landed safely on the Red Planet and was soon taking a look around.

I didn’t ‘Wave at Saturn’ on 19 July when the Cassini probe, orbiting the gas giant, was taking a high-definition image of the view back home. I don’t think it encouraged a proper sense of perspective… But the resultant image is stunning. [Image Credit: NASA/JPL-Caltech/Space Science Institute] It’s not the first time Cassini has looked home. Nor more…

If you enjoyed the recent video from Nasa’s Solar Dynamics Observatory (SDO) – “Three years in three minutes” – but would have liked more of an explanation of what was going on with our own local star… here it is again! This time, though, extended, and narrated by NASA’s Goddard Space Flight Center heliophysicist Alex Young. more…

As I mentioned previously, Saturn doesn’t get the love some of our other gas giants do. [All hail our friend and lord, Jupiter! Keeping Ogdy at bay… – Ed] Indeed… [new link] But, with the help of Cassini, Saturn does provide some wondrous images. In some of its first sunlit images of Saturn’s north pole, Cassini has looked inside more…

What it says on the tin. Three years after First Light, Nasa’s Solar Dynamics Observatory (SDO) has released three stunning minutes of images compiled during its virtually unbroken coverage of the sun’s rise toward solar maximum. Enjoy! [Video from NasaExplorer on YouTube. Credit: NASA’s Goddard Space Flight Center/SDO] As they note in the associated text During more…

Here’s something to think about whilst waiting to see if Comet ISON will fizzle, or sizzle. The latest Science at Nasa video looks at the trajectory, and consequences for Mars missions, of Comet 2013 A1 (Siding Spring). Discovered as recently as 3 January this year, this Oort cloud object will pass “extraordinarily close” to the planet Mars on more…

As the BBC reported on Wednesday, having opened its eyes in 2011, and with 57 of its 66 antennas now ready to receive data on the Chajnantor Plateau in the Atacama desert, Chile, the Atacama Large Millimetre/Sub-millimetre Array (ALMA) was officially inaugurated on March 13.
